分数“膨胀”

Directions
Study the graphs below and write a short composition explaining its significance in aborn 120 words. The graphs compare the percentages of A, B, C, and D grades at Stone Monntain Jr. College in the fall semesters of 1968 and 1978.

Grade "Inflation"
From the graphs, we can see that grades have been rising rapidly. It can well be said that there is a grade "inflatiou."
Take, for example, the Stone Mountain Jr. College. In the fall semester of 1968, 16% of the students taking the exams received A＇s. However, in 1978, within ten years, the percentage went up by 13%. Twenty nine percent of the students received A＇s. As for the B grade studems, in 1968, the percentage was 31%. Ten years later, the percentage dropped to 26%. There was a 5% decrease, or rather, the students＇ grades rose by 5 %.
Now let us have a look at the third graph, which shows that in 1968 37% of the examinees received C＇s while in 1978 the ratio fell to 21%. In other words, there was a 16% rise in grades.
And in the forth graph, we can see that 8% of the students received D＇s. In 1978 only 4% of the examinees are D grade students. That means the grades doubled within ten years as compared to that of 1968.
The grade "inflation" puts me upon thinking whether students are working harder than ever or the teachers are being. lenient or cheating is on the rise. I hope for the beat.
分数“膨胀”
从图表中，我们可以看到分数在迅速上升，也可以说是分数澎胀”。
例如，石头山专科学校，1968年秋季，16%的考生得A等。然而，到1978年，在10年中，百分比上升13%，有29%的考生得A等。
至于得B等学生，1968年是31%，10年后下降到26%，减少5%。或者说，学生的分数上升5%。再看第3表：1968年有37%的考生得C等，而在1978年比例降到21%。换言之，分数上升16%。
在第4表中，我们看到有8％考生得D等，而1978年仅有4%考生得D等。这就意味着10年中分数翻1番。
分数“膨胀”，使我想到是否学生更用功，还是老师更宽容，或者作弊现象在上升。我希望是最好的。
